Highlights
- Fires to cone 5-6; apply to bisqueware fired to cone 04
- Soft black to olive green to rust red as the coat gets heavier
- Reds on all clay bodies; iron-bearing clays give the widest range
- No special cooling or soak needed (a soak can dull the reds)
- ACMI AP seal (conforms to ASTM D-4236); AMACO rates it for spray application
- AMACO Food Safe seal: tested for lead and cadmium release per ASTM C738-94
How to apply it
- 1
Start with clean bisqueware fired to cone 04.
- 2
Load a soft, natural-fiber fan brush and float each coat on; reload when the brush starts to drag.
- 3
Apply it on the heavy side, 3-4 coats with each dried completely, to bring out the reds.
- 4
It's a fluid glaze: fire a test tile on your clay first to see how far it moves.
- 5
Glaze fire to cone 5 (2167°F) or cone 6 (2232°F) at medium speed. Skip any hold or soak, which can dull the reds.
- 6
For layering, AMACO's guide uses 2 brushed coats of each Potter's Choice glaze.

About this glaze
Ancient Jasper is an opaque, moving glaze whose color depends on how much you put on: a thin coat reads soft black, and heavier coats shift through olive green to rust red. The surface is active and varied on its own and striking when layered with other Potter's Choice glazes. AMACO says it gives reds on any clay body, with the widest color range on iron-bearing clays, and it needs no special cooling cycle or soak; a soak can actually dull the reds. Fires to cone 5-6. Brush it straight from the pint jar. Carries the ACMI AP seal and AMACO's Food Safe seal.
